Title (EN) POWER CONVERTING SYSTEM
(FR) SYSTÈME DE CONVERSION DE PUISSANCE
(JA) 電力変換システム
Abstract:
(EN) The objective of the present disclosure is to reduce power loss due to switching. A control unit (7) controls an inverter circuit (5) such that positive and negative voltages are applied alternately to a primary winding (19). During a first period including a reversal period in which the polarity of the voltage in the primary winding 19 is reversed, the control unit 7 controls a cyclo-converter (11) such that power is not transferred between the cyclo-converter (11) and the inverter circuit (5). During a second period different from the first period, the control unit (7) controls the cyclo-converter (11) such that power is transferred in a first direction from the cyclo-converter (11) toward the inverter circuit (5) or in a second direction opposite to the first direction.
(FR) L'objet de la présente invention est de réduire la perte de puissance due à la commutation. Une unité de commande (7) commande un circuit onduleur (5) de telle sorte que des tensions positive et négative sont appliquées en alternance à un enroulement primaire (19). Pendant une première période comprenant une période d'inversion dans laquelle la polarité de la tension dans l'enroulement primaire 19 est inversée, l'unité de commande 7 commande un cyclo-convertisseur (11) de telle sorte que la puissance n'est pas transférée entre le cyclo-convertisseur (11) et le circuit onduleur (5). Pendant une seconde période différente de la première période, l'unité de commande (7) commande le cyclo-convertisseur (11) de telle sorte que la puissance est transférée dans une première direction du cyclo-convertisseur (11) au circuit onduleur (5) ou dans une seconde direction opposée à la première direction.
(JA) 本開示の目的は、スイッチングによる電力損失を低減することである。制御部(7)は、一次巻線(19)に正及び負の電圧が交互に印加されるようにインバータ回路(5)を制御する。制御部7は、一次巻線19の電圧の極性が反転する反転期間を含む第1期間において、サイクロコンバータ(11)とインバータ回路(5)との間で電力の伝達が行われないようにサイクロコンバータ(11)を制御する。制御部(7)は、第1期間とは異なる第2期間において、サイクロコンバータ(11)からインバータ回路(5)に向かう第1方向又は第1方向とは逆の第2方向で電力の伝達が行われるようにサイクロコンバータ(11)を制御する。
